She should know. I hear she can see Egypt from her house.
Well, it only says "still have." Nothing about readability there!
Now get off my front lawn!
Or did you mean written by me?
But health care to housing is something like 1:2...
Theories remain theories, period.
Yeah, the person misusing the word above falls into the Princess Bride category -- "I don't think that word means what you think it means."
On a "good" sail the surface is very reflective. The force that propels the spacecraft is the sum of two vectors; one pointing from the sun to the spacecraft, and a second for the reflected radiation leaving the sail. So you can steer the spacecraft by shortening one side and lengthening the other side of the says attaching the sail to the spacecraft, redirecting the outgoing vector. Or do something similar (e.g. reorient segments rather than the whole sail).
It's more likely that the flight engineers would just add course corrections in (i.e. change the sail orientation to redirect the force) if they had a specific target in the Oort cloud in mind.
Just as small errors due to GR get magnified over the long trajectory, so do small corrections get magnified if made early enough. And, as one earlier commenter noted, a million km isn't much of anything at these distances.
